-I claim- 1. The 'prtwess of treating and refining oil for the purpose of transforming heavy ln'droearbuu oils into lighter hydrocarbon lls which comprises heating a body of saicl heavy lrvrlrmmrbou nil in a suitable rouliaitltl to a temperature sutiieient to develop a pres ure not ltrS than 400 pounds per square inch and not n l-eater 'than1000 pounds per square int-h. passiu the evolved vapors .orer and in contact with a sulticient body of heary'hyd-rocarhon oil to separate. the heavy lrvilrocarbous in the vaporphase from the light h vdrotarbous. the said bodr of heavy lrrdrocurbou, oil being utaiut'ained under the same pressure as that prevailing in the firs na-ntioued body of oil but being at a temln-rature somewhat less. and continuously su nilyi'ug fresh oil to said. second body and passing oil from said second-body to said first bodyQ 2. The processof oil for thepm'pose of tranfs orming hezw-y hydrocarbon oi sinto lighter hydrocarbon o'ils'wb'ich'comprises heating a o-f said hearyhydrocarbon oil in a suitable container to a temperature not less than 300 C. and no]: inoret-han 450 C. and under a pres sure to develop vapor of not less than 400 pmunlsper tare inch and not; more than .1000 pounds jpe'ri'sqtiare. incb passing the atoll-ed mm-s .orer and "in" cont mwith a. sufli ie'nt' bod or ta-arjv. hydrocarbon oil to separate the, lltttvt', ln droca-rbous-in the "vaporgphasctfrolu the light hydrocarbons. the

It, The proees of trentinghear. petroleum oil whieh comprises establishing and maintainiuga body of heated heavy oil at a temperature between 300 uudtia'itl C. and under a pressure betweeu400 pounds and Luuo pounds per square inch, continuously supplying heated oil to such body from a Hr'ontl body of oil under the same pressure but at a less temperature. removing the rapnrs from the. first mentioned body of oil. transmitting them over the second body of oil and; then condensing, therebeing a feed of fresh heavy oil to the second stated body and thence. to the. first stated body in protreat-in and refining 7 portion to the disappearance of oil due [u the formation of such \21 era and a suflL rieut withdrawal of oil Sudge. to prevent excessive deposition of carbon.

47 The proeessof treating heaaypetroleum oil which comprises establishing and |uaiutaiuing a body of heated heavv oil at a term perature. between 300 C. and 450 C. and under a pressure between 400 pounds and 1000 pounds per square inch, eontinuouslv supplying heated oil to such body from i1 second body of oil under the same pressurebut at a less tennierature. reutovin the. vapors from the. first. mentioned l')0( V of-oil, transmitting them over the. second bodv of oil and then condensing, there being a feed of fresh heavy oil to the second stated body and thence. to the first stated body in proportion to the disappearance of oil clue to the formation of such vapors.
